BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is directed to certain hydroxamate derivativesthat are useful in the treatment of hepatitis C. These compounds arealso inhibitors of histone deacetylase and are therefore useful in thetreatment of diseases associated with histone deacetylase activity.Pharmaceutical compositions and processes for preparing these compoundsare also disclosed.

2. State of the Art

Hepatitis C:

Chronic hepatitis C is a slowly progressive disease having a significantimpact on morbidity and mortality. While many patients who contracthepatitis C will have sub clinical or mild disease, at least 80% of theindividuals who contract HCV develop chronic infection and hepatitis.Twenty to fifty percent of these eventually progress to cirrhosis and1-2% develop liver cancer (Hoofnagle, J. H.; 1997; Hepatology 26:15S-20S). There are an estimated 170 million HCV carriers world-wide,and HCV-associated end-stage liver disease is now one of the leadingcause of liver transplantation. In the United States alone, hepatitis Cis responsible for 8,000 to 10,000 deaths annually.

At the present time, interferon-α2b/ribavirin combination therapy is theonly available treatment. Sustained virologic response toIFN-α2b-ribavirin combination therapy occurs in about 40-45% of thosetreated. For those patients who fail interferon-α2b/ribavirincombination therapy, there is currently no alternative to prevent theprogression of liver disease. Thus, a need exists for alternativetherapies for the treatment of chronic HCV infection. The presentinvention fulfills this need.

Histone Deacetylases:

Interest in histone deacetylase enzymes (HDACs) as targets forpharmaceutical development has centered on the role of HDACs inregulating genes associated with cell-cycle progression and thedevelopment and progression of cancer (reviewed in Kramer et. al. 2001.Trends Endocrinol. Metab. 12:294-300). Several studies have shown thattreatment of various cell lines with HDAC inhibitors leads to hyperacetylation of histone proteins and cell-cycle arrest in late G₁ phaseor at the G₂/M transition. Genes involved in the cell cycle that havebeen shown to be up regulated by HDAC inhibitors include p21, p27, p53and cyclin E. Cyclin A and cyclin D have been reported to be downregulated by HDAC inhibitors. In tumor cell lines, several studies haveshown that treatment with HDAC inhibitors can lead to growth inhibition,growth arrest, terminal differentiation and/or apoptosis. In vivostudies have demonstrated growth inhibition of tumors and a reduction intumor metastasis as a result of treatment with HDAC inhibitors.

The clearest link between abnormal HDAC activity and cancer occurs inacute promyelocytic leukemia. In this condition, a chromosomaltranslocation leads to the fusion of the retinoic acid receptor RARαwith the promyelocytic leukemia (PML) or promyelocytic leukemiazinc-finger (PLZF) proteins. Both PML-RARα and PLZF-RARα promote theprogression of leukemia by repressing retinoic acid-regulated genesthrough the abnormal recruitment of SMRT-mSin3-HDAC complex (Lin et.al., 1998, Nature 391:811-814; Grignani et al., 1998, Nature391:815-818). Whereas the PML-RARα form of the disease is treatable withretinoic acid, the PLZF-RARα form is resistant to this treatment. For apatient with the retinoic acid-resistant form of the disease, theaddition of the HDAC inhibitor sodium butyrate to the dosing regimen ledto complete clinical and cytogenic remission (Warrell et al., 1998, J.Natl. Cancer. Inst. 90:1621-1625). HDACs have also been associated withHuntington's disease (Steffan, et al., Nature 413:739-744, “Histonedeacetylase inhibitors arrest polyglutamine-dependent neurodegenerationin Drosophila”).

In summary, an increase in HDAC activity contributes to the pathologyand/or symptomatology of a number of diseases. Accordingly, moleculesthat inhibit the activity of HDAC are useful as therapeutic agents inthe treatment of such diseases.

These schemes aremerely illustrative of some methods by which the compounds of thisinvention can be synthesized, and various modifications to these schemescan be made and will be suggested to one skilled in the art havingreferred to this disclosure. The starting materials and theintermediates of the reaction may be isolated and purified if desiredusing conventional techniques, including but not limited to filtration,distillation, crystallization, chromatography and the like. Suchmaterials may be characterized using conventional means, includingphysical constants and spectral data.

Unless specified to the contrary, the reactions described herein takeplace at atmospheric pressure over a temperature range from about −78°C. to about 150° C., more preferably from about 0° C. to about 125° C.and most preferably at about room (or ambient) temperature, e.g., about20° C.

Compounds of Formula (I) where X is —O— or —S(O)_(n)— where n is 0 to 2and other groups are as described in the Summary of the Invention can beprepared by the procedure illustrated and described in Scheme A below.

Reaction of a compound of formula I where R is alkyl, X is —O— or —S—and Ar¹ is as defined in the Summary of the Invention with anaminoalcohol of formula 2 where PG is a suitable amino protecting groupprovides a compound of formula 3. The reaction is carried out in thepresence of triphenylphosphine and diisopropyl azodicarboxylate in asuitable organic solvent such as tetrahydrofuran, and the like.

Compounds of formula I such as methyl 4-hydroxybenzoate, methyl4-mercaptobenzoate, and methyl 3-hydroxyisoxazole-5-carboxylate arecommercially available. Compounds of formula 2 can be prepared fromcommercially available aminoalcohols by reacting the amine with asuitable amino protecting group such as benzyloxycarbonyl,tert-butoxycarbonyl and the like under reaction conditions well known inthe art. A detailed description of suitable amino protecting groups andreaction conditions for their preparation can be found in T. W. Greene,Protecting Groups in Organic Synthesis, John Wiley & Sons, Inc. 1981 theteaching of which is incorporated herein by reference in its entirety.Aminoalcohols such as 2-ethanolamine, 2-amino-1-propanol,2-methylaminoethanol, 2-amino-2-methyl-1-propanol, 2-amino-1-propanol,4-amino-2-butanol, and 1-amino-2-butanol are commercially available.Alternatively, compounds of formula 2 can be prepared from commerciallyavailable aminoacids by protecting the amino group with a suitableprotecting group followed by reduction of the acid group to the hydroxygroup with a suitable reducing agent under conditions well known in theart. If compounds of Formula (I) where X is —SO₂— are desired, thecorresponding compound of formula 3 where X is —S— can be treated withan oxidizing agent such as OXONE®, m-chloroperbenzoic acid, and thelike.

Removal of the amino protecting group in 3 provides a compound offormula 4. The reaction conditions employed for removal of the aminoprotecting group depend on the nature of the protecting group. Forexample, if the protecting group is tert-butoxycarbonyl, it is removedunder acid reaction conditions. Suitable acids are trifluoroacetic acid,hydrochloric acid, and the like in a suitable organic solvent such asmethanol, dioxane, tetrahydrofuran, and the like. If the protectinggroup is benzyl or benzyloxycarbonyl, it is removed under catalytichydrogenation reaction conditions. Suitable catalyst are palladium basedcatalysts and others known in the art. Other suitable reactionconditions for their removal can be found in T. W. Greene, ProtectingGroups in Organic Synthesis, John Wiley & Sons, Inc. 1981. The reactionis carried out in an inert organic solvent methylene chloride,tetrahydrofuran, dioxane, and the like.

Reaction of 4 with an acid or acid derivative (e.g., acid halide) offormula Ar²-COZ where Z is hydroxy or halo provides a compound offormula 5. Again, the reaction conditions employed depend on the natureof the Z group. If Z is hydroxy, the reaction is typically carried outin the presence of a suitable coupling agent e.g.,benzdtriazole-1-yloxy-trispyrrolidino-phosphonium hexafluorophosphate(PyBOP®), O-benzotriazol-1-yl-N,N,N′,N′-tetramethyl-uroniumhexafluorophosphate (HBTU),O-(7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluroniumhexafluorophosphate (HATU),1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC. HCl),or 1,3-dicyclohexylcarbodiimide (DCC), optionally in the presence of1-hydroxybenzotriazole hydrate (HOBT.H₂O), and a base such asN,N-diisopropylethylamine, triethylamine, N-methylmorpholine, and thelike. The reaction is typically carried out at 20 to 30° C., preferablyat about 25° C., and requires 2 to 24 hours to complete. Suitablereaction solvents are inert organic solvents such as halogenated organicsolvents (e.g., methylene chloride, chloroform, and the like),acetonitrile, N,N-dimethylformamide, ethereal solvents such astetrahydrofuran, dioxane, and the like. Preferably, the reaction iscarried out with HOBt. H₂O, EDC.HCl in dichloromethane orN,N-dimethylformamide.

When Ar²COZ is an acid halide, the reaction is carried out in thepresence of a suitable base (e.g. triethylamine, diisopropylethylamine,pyridine, and the like). Suitable reaction solvents are polar organicsolvents such as tetrahydrofuran, acetonitrile, N,N-dimethylformamide(DMF), dichloromethane, or any suitable mixtures thereof. The acidhalide such as acid chloride can be prepared by reacting thecorresponding acids with a halogenating agent such as oxalyl chloride,thionyl chloride, phosphorus oxychloride, and the like. Acids of formulaAr²COZ are either commercially available or they can be prepared fromcommercially available starting materials by methods known in the art.For example, benzoic acid, cinnamic acid, phenylacetic acid, nicotinicacid, isonicotinic acid, 3-methylbenzofuran-2-carboxylic acid, andbenzofuran-2-carboxylic acid are commercially available. Others such as3-phenoxymethylbenzofuran-2-carboxylic acid can be readily prepared fromcommercially available 3-methylbenzofuran-2-carboxylic acid by firstconverting it to 2-bromomethylbenzofuran-2-carboxylic acid (brominatingit with N-bromosuccinimide under conditions well known in the art)followed by reacting with phenol. Compound 5 where R³ is hydrogen canoptionally be converted to a corresponding compound of formula 5 whereR³ is other than hydrogen by reacting it with an alkylating agent underconditions well known in the art.

Compound 5 is then converted to a compound of Formula (I) by reacting itwith aqueous hydroxylamine in the presence of a base such as sodiumhydroxide and a mixture of organic solvents such as tetrahydrofuran andmethanol. Alternatively, the acid group in 5 is first activated with asuitable coupling agent such as1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC. HCl),or 1,3-dicyclohexylcarbodiimide (DCC), optionally in the presence of1-hydroxybenzotriazole hydrate (HOBT.H₂O) in a suitable organic solventsuch as dimethylformamide, and the like, and then reacted withhydroxylamine hydrochloride in the presence of a base such asN,N-diisopropylethylamine, triethylamine, N-methylmorpholine, and thelike. Compounds of Formula (I) can also be prepared from compound 5 bythe methods disclosed in U.S. Pat. No. 5,998,412, the disclosure ofwhich is incorporated herein by reference in its entirety.

A compound of Formula (I) can be converted to other compounds of Formula(I). For example, a compound of Formula (I) where Ar¹ is phenylene, X is—O—, Y is ethylene, Ar² is 3-dimethylaminomethylbenzofuran-2-yl, R¹ andR³ are hydrogen can be prepared by reacting a compound of formula 4where Ar¹ is phenylene, X is —O—, Y is ethylene, and R is alkyl with3-methylbenzofuran-2-carboxylic acid as described above to give acompound of formula 5 where Ar² is 3-methylbenzofuran-2-yl. Brominationof the methyl group with a suitable brominating agent such asN-bromosuccinimide, followed by reaction with dimethylamine provides thecorresponding 3-dimethylaminobenzofuran-2-yl compound which is thenconverted to the desired compound under the reaction conditionsdescribed above.

Oral compositions cantake the form of tablets, pills, capsules, semisolids, powders,sustained release formulations, solutions, suspensions, elixirs,aerosols, or any other appropriate compositions.

The choice of formulation depends on various factors such as the mode ofdrug administration (e.g., for oral administration, formulations in theform of tablets, pills or capsules are preferred) and thebioavailability of the drug substance. Recently, pharmaceuticalformulations have been developed especially for drugs that show poorbioavailability based upon the principle that bioavailability can beincreased by increasing the surface area i.e., decreasing particle size.For example, U.S. Pat. No. 4,107,288 describes a pharmaceuticalformulation having particles in the size range from 10 to 1,000 nm inwhich the active material is supported on a crosslinked matrix ofmacromolecules. U.S. Pat. No. 5,145,684 describes the production of apharmaceutical formulation in which the drug substance is pulverized tonanoparticles (average particle size of 400 nm) in the presence of asurface modifier and then dispersed in a liquid medium to give apharmaceutical formulation that exhibits remarkably highbioavailability.

The compositions are comprised of in general, a compound of Formula (I)in combination with at least one pharmaceutically acceptable excipient.Acceptable excipients are non-toxic, aid administration, and do notadversely affect the therapeutic benefit of the compound of Formula (I).Such excipient may be any solid, liquid, semi-solid or, in the case ofan aerosol composition, gaseous excipient that is generally available toone of skill in the art.

Solid pharmaceutical excipients include starch, cellulose, talc,glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silicagel, magnesium stearate, sodium stearate, glycerol monostearate, sodiumchloride, dried skim milk and the like. Liquid and semisolid excipientsmay be selected from glycerol, propylene glycol, water, ethanol andvarious oils, including those of petroleum, animal, vegetable orsynthetic origin, e.g., peanut oil, soybean oil, mineral oil, sesameoil, etc. Preferred liquid carriers, particularly for injectablesolutions, include water, saline, aqueous dextrose, and glycols.

Compressed gases may be used to disperse a compound of this invention inaerosol form. Inert gases suitable for this purpose are nitrogen, carbondioxide, etc.

Example 4 Synthesis of acetyl-Gly-Ala-(N-acetyl-Lys)-AMC

tert-Boc (N-Acetyl-Lys)-AMC (445 mg, 1 mmol, purchased from Bachem) wasdissolved in 4 M HCL in dioxane to provide H-(N-acetyl-Lys)-AMC as awhite solid. To a solution of H-(N-acetyl-Lys)-AMC in DMF (5 ml) wasadded Ac-Gly-Ala-OH (188 mg, 1 mmol) using PyBOP (520 mg, 1 mmol), HOBt(135 mg, 1 mmol), and NMM (0.296 ml, 2 mmol). The reaction mixture wasstirred for 1 h and monitored by MS/LC for the presence ofH-(N-acetyl-Lys)-AMC. Additional amounts of PyBOP (260 mg, 0.5 mmol),HOBt (70 mg, 0.5 mmol), and NMM (0.146 ml, 1 mmol) was added and thestirring was continued for additional 4 h after which the product wasisolated in quantitative yield.

Biological Examples Example 1 Inhibition of HDAC In Vitro

The HDAC inhibitory activity of the compounds of this invention in vitrowas determined as follows.

Measurements were performed in a reaction volume of 100 μL using 96-wellassay plates. HDAC-1 (200 μM final concentration) in reaction buffer (50mM HEPES, 100 mM KCl, 0.001% Tween-20, 5% DMSO, pH 7.4) was mixed withinhibitor at various concentrations and allowed to incubate for 30minutes, after which trypsin and acetyl-Gly-Ala-(N-acetyl-Lys)-AMC wereadded to final concentrations of 50 nM and 25 μM, respectively, toinitiate the reaction. Negative control reactions were performed in theabsence of inhibitor in replicates of eight.

The reactions were monitored in a fluorescence plate reader. After a 30minute lag time, the fluorescence was measured over a 30 minute timeframe using an excitation wavelength of 355 nm and a detectionwavelength of 460 nm. The increase in fluorescence with time was used asthe measure of the reaction rate. Inhibition constants were obtainedusing the program BatchKi (Kuzmic et al. Anal. Biochem. 2000, 286,45-50). Most of the compounds of this invention had a Ki of <40 nm.

Example 2 Cell Proliferation Assay In Vitro

The ability of the compounds of Formula (I) to inhibit growth of tumorcells in vitro was determined as follows.

Stock cultures of the HCT116 colon carcinoma cell line were maintainedin RPMI medium 1640 containing 10% (v/v) fetal bovine serum, 2 mML-glutamine, 1 mM sodium pyruvate, 50 units/ml penicillin, and 50 μg/mlstreptomycin at 37° C. in 5% CO₂ humidified atmosphere. Cells werecultured in 75-cm² culture flasks and subcultures were established every3 to 4 days so as not to allow the cells to exceed 90% confluence.

HCT116 cells were harvested for proliferation assays by trypsinization(0.05% trypsin/0.53 mM EDTA), washed twice in culture medium,re-suspended in appropriate volume of medium, and then counted using ahemacytometer. Cells were seeded in wells of flat-bottom 96-well platesat a density of 5,000 cell/well in 100 μl. Cells were allowed to attachfor 1.5 to 2 hours at 37° C.

Compounds were diluted from 10 mM stock solutions in DMSO. Serial 3-folddilutions were performed in medium containing 0.6% DMSO in wells (intriplicate) of a 96-well U-bottom plates starting with a 60 μM solution.After dilutions were completed, 100 μl of each compound dilution (intriplicate) was transferred to designated triplicate wells of the96-well plate containing cells in 100 μl of medium. Final concentrationsof the dose-response for compounds in assay plates ranged from 0.12 to30 μM. Control wells (cells with no treatment) received 100 μl of 0.6%DMSO in culture medium. Wells containing medium with no cells served asthe background wells. Cells were cultured with the compounds for 48 and72 hours at 37° C. in a humidified CO₂ incubator.

Cell proliferation was assessed by measuring fluorescence after theaddition of the fluorogenic redox indicator, Alamar Blue™ (BioSourceInternational). Ten μl of Alamar Blue™ was added to each well of the96-well plate(s) 3 to 4 hours prior to the end of the incubation period.Assay plates were read in a fluorescence plate reader (excitation, 530nM; emission, 620 nM). G_(I50) values (concentration at which the growthof the tumor cells was inhibited by 50%) for compounds were determinedby plotting the percent control fluorescence against the logarithm ofthe compound concentration. The compounds of this invention inhibitedthe growth of the tumor cells.
